Camptosomate leaf beetles share an amazing building behavior in which female beetles wrap their eggs in plates of fecal material forming a case. The larvae remain in this case, carrying it over their backs and enlarging and elaborating it until pupation. This study is the first fully detailed study that evaluates the adaptive function provided by the fecal cases of this group. The cases of one camptosomate in particular, Neochlamisus platani, contain architectural aspects not normally found in other beetles, i.e. incorporation of trichomes into the outside of the case and trichomes stored in a special compartment within the case, the "trichome attic" (currently only known in this species). The objectives of this study are to determine whether or not the unique aspects of animal architecture found in N. platani cases individually or in combination provide protection from arthropod predators using multiple generalist predators of different orders and feeding habits. Continuous observation trials allow the evaluation and recording of a range of mechanisms and behaviors associated with this fascinating example of animal architecture that contribute to the survival of N. platani larvae.
